Specification of Letters Patent.

Application filed February 12, 1906. Serial No. 300,795.

To all whom, it may concern:

. Be it known that I, HERMAN W. PICKARD, a citizen of the United States, residing at the city of Oshkosh, in the county of Winnebago and State of Wisconsin, have invented new and useful Improvements in Milk Bottle Skimmers, of which the following is aspecifi- My invention relates to an appliance for skimming milk from bottles.

Milk is now usually delivered to the consumer in bottles; and my invention provides a means for skimming the cream from the milk while in the bottle. It is ordinarily impossible to introduce an appliance into the ottle without displacing the milk so that it will run over the top of the bottle. Bottles are usually filled nearly full.

My apparatus provides a skimmer ada ted to admit cream either at the top or the ottom at the option of the operator.

In the accompanying drawing, Figure 1 illustrates a vertical section of my invention, and Fig.2 is a side view.

Referring to the drawings by numerals, the container 2 comprises a tapered or conoida] hollow shell, having its lower end 3 the smaller and provided with a valve member 4, disposed within the container and proportioned to fit and close the opening 8 in the lower smaller end of the container. The upper end 7,0f the container is the larger and is provided with a handle portion 9, secured diametrically u on opposite sides of the container and exten ing upwardly from the said end 7 in substantial arallelism and formed with an enlarged or Eowed portion at the top, integral with the parallel side portions.

The valve member 4 is provided with'a stem 5, extending upwardly through the container 2 and between the parallel side portions of the handle 9 and through an opening formed in the upper bowed portion of the handle in alinement with the axis of the container 2. The stem 5 having assed through the upper portion-of the handle 9, is provided wit a ring or finger-engaging portion'fi upon the outer and upper side of the said handle and in position to permit the insertion of the finger when the remaining lingers grasp the bowed portionof the handle.

In a bottle of milk cream rises at the top. Usingmy invention the operator grasps the handle 9 with his fingers, inserts his thumb in the thumb-handle 6, raises the valve 4, and

inserts the container in the bottle. Thevalve being open the cream rises in the container. This process is only for partialextraction of the cream. When the =operator considers it proper, he closes the valve by loweringhis thumb and withdraws the container with a small amount of cream and by raising the valve 4 with his thumb deposits the cream in any receptacle. Then he closes the bottom of the container 2 by pressing downwardly the valve 4 with his thumb and inserts the Patented Feb. 26, 1907.

container in the bottle of milk. The insertion of the container will then not cause the milk to run over the top. The valve 4 is then closed, and the cream is allowed slowly to run over the top into the container 2 by pressing downwardly until the milk is fully skimmed. Then the container may be removed and the valve opened to deposit in any receptacle.

Having thusdescribed my invention, what I claim, and desire to secure by Letters Patent,'ise

A skimmer comprising .a container tapered throughout its length, a plunger disposed within the container, and proportioned to fill and close the small end, a handle having its ends secured to the large end and extending above the container in bowed form wider than the container, a plunger-rod secured to the plunger and extending slidably u ward through the handle, and a ring forme upon the upper extremity of the plunger-rod.

In testimony whereof I afiix my signature "in presence of two subscribing witnesses.

HERMAN w; PICKARD.
